T775A,B,C,D
SPECIFICATIONS
CONTACT RATINGS:
1/2 hp; 9.8 FLA, 58.8 LRA at 120 Vac.
1/2 hp; 4.9 FLA, 29.4 LRA at 240 Vac.
125 VA pilot duty at 120/240 Vac.
10A at 24 Vac (resistive).
SENSOR: Positive coefficient platinum type, 4.8 ohms/ °F,
1000 ft maximum distance between sensor and solid
state controller (requires calibration over 400 ft). To
maintain NEMA 4X rating, use environmental proof
cable and sensor.
TEMPERATURE ACCURACY: +/-1°F (at nominal volt-
age in 77°F [25°C] ambient, nominal sensor value). Accu-
racy may vary based on deviation from nominal values of
input voltage, operating ambient and sensor ambient.
DISPLAY RESOLUTION: Sensed temperature and other
operating parameters are displayed via a liquid crystal
display (LCD) with a resolution of 1°F or 1°C.
SETPOINT ADJUSTMENT RANGE: -40° to 220°F (-40°
to 104°C).
OPERATING AMBIENT TEMPERATURE:
One and Two Stage units: -30° to 140°F.
Three and Four Stage units: -30° to 125°F.
OPERATING HUMIDITY: 5% to 95% relative humidity
(RH) noncondensing.
APPROVALS:
Underwriters Laboratories Inc. Listed: File no. E4436.
Canadian Standards Assoc. certified: File no. LR47125.
DIMENSIONS: See Fig. 1 and 2.
MOUNTING: Mounts on any suitable horizontal or vertical
surface (see Fig. 3 and 4 for mounting hole locations).
